NumericaLTI — Interactive Solver

Method

Newton-Raphson

Equation f(x)

x^2 - 2

Initial Guess x₀

1.0
Solve →

Convergence

Initialize: x₀ = 1.000000

f(x₀) = −1.0000e+0, f′(x₀) = 2.0000e+0

Iter 1: x₁ = 1.50000000

Error: |x₁ − x₀| = 5.0000e−1

Iter 2: x₂ = 1.41666667

Error: |x₂ − x₁| = 8.3333e−2

Iter 3: x₃ = 1.41421356

Error: |x₃ − x₂| = 2.4510e−3

Iter 4: x₄ = 1.41421356

Error: |x₄ − x₃| = 1.5943e−12

✓ Converged in 4 iterations

Root ≈ 1.41421356 (√2 exact)

Quadratic convergence: notice digits doubling each step

Security & Privacy

Built for institutional use. We collect only what's needed and protect it at every layer.

Encrypted in Transit

All traffic over HTTPS/TLS. Canvas JWTs verified server-side via JWKS on every launch — tokens never touch the client.

Row-Level Security

Supabase PostgreSQL with RLS policies enforced at the database layer. Students can only read their own submissions.

Minimal PII

We store name, institutional email, and course enrollment. No Social Security numbers, grades beyond NumericaLTI, or payment details.

LTI 1.3 Standard

OIDC-based launch flow with state and nonce validation. Replay attacks blocked by one-time cookie verification.
